- the functional classification of the Anchor capsules 2; 2 'now take place in two stages.
- the anchor 1 is inserted into the anchor capsule 2 in the manner already illustrated and brings the chemicals into the depth L1 after reaching the pressure plate 18 C1; C2 for reaction.
- the pressure plate 18 is not loaded by the armature 1.
- the armature 1 is rotated and presses the pressure plate 18 to the chamber 20.
- the reaction elements 19 activate the reactant 17 in the chamber 20, which produce the excavation 16 over the length L2, now the cavity 9 is increased by the difference from d1 to d2.
- the excavation 16 arises and by the penetration of the armature 1 beyond the pressure plate 18.
- the anchor 1 can according to 2 find use.
- FIG. 5 shows an embodiment of the anchor capsule 2.
- the anchor capsule 2 horizontally and vertically running predetermined breaking points 22 are arranged.
- the inner surfaces 25 of the anchor capsule 2 carry cams 26, 27, which are intended to prevent independent twisting and shearing of the non-positive and positive connection on the walls of the capsule 2 and are suitable for introducing greater axial tensile forces into the anchor.
